LIVE Keep it cold

2–6°CLive Quas lives in the fridge.

Live Quas is unpasteurised, so its cultures stay active. The cold slows them down and keeps the flavour where it should be.

Chill it on arrival.

Unpack your box and put every can straight into the fridge. Live Quas must stay refrigerated at all times.
It keeps evolving.

The cultures stay active in the cold, so Quas slowly becomes more sour and less sweet with time.
Enjoy within six weeks.

Live Quas keeps for six weeks. Check the best-before date on the can.

What people say after tasting Quas.

Loading Google reviews...

What does Quas taste like?

Malty and tangy, with a clean, dry finish. Original leans towards dried fruit and gentle spice, Ginger brings fresh ginger warmth, and Mint & Lime is bright and zesty.

Can I mix flavours in one box?

Yes. Choose two or all three flavours in the picker above and we will split your box between them.

What is kvass?

Kvass is a traditional fermented drink made from rye and barley. Quas is our sourdough fermented take on it, made in Scotland.

Is Quas like beer?

It shares beer's malty grains and natural carbonation, so it sits comfortably alongside a pint. It is fermented with a sourdough culture, so it tastes tangier and finishes dry.

Is Quas alcoholic?

Quas is a non-alcoholic fermented drink. Always check the product label for the exact declaration on the can you buy.

How long does Live Quas keep?

Live Quas keeps for six weeks in the fridge at 2–6°C. It slowly becomes more sour and less sweet over time, which is the cultures at work.

Why does Live Quas need the fridge?

Live Quas is unpasteurised, so its cultures stay active. The cold slows them down and keeps the flavour where it should be. Store it at 2–6°C at all times.

Is Quas vegan?

Yes. Quas is plant-based and suitable for vegans. It contains gluten from rye and barley.

How much sugar is in Quas?

Original has 2.4g of sugars per 100ml, and Ginger and Mint & Lime have 2.5g, so every flavour is low in sugar.
